The Common Information Model CIM acceptedimplemented Globally for

The Common Information Model (CIM) accepted/implemented Globally- for operations, planning, markets, and throughout the Enterprise David Becker, EPRI Presented at the “ 2005 EMS Users Group Meeting” Providence, R. I. September 13, 2005

History of the Common Information Model (CIM) • Late 1980’s-Early 90’s- Informal meetings of Industry focused on “How to achieve “open system design” • 1993 -Formation of EPRI led CCAPI Task Force: “ One vendor did not have all solutions for a customer. Need for integration” • Initial Goals of CCAPI: – Provide common information model to facilitate information exchange – Enable use of plug in applications – Protect application investment – Framework for integration of legacy systems © 2005 Electric Power Research Institute, Inc.

Important Milestones • 9/1996: CIM initially submitted to IEC; CIM 10 final version accepted for standard in 2001. First major CIM Installation 1998 • Component technology emerged in late 1990’s. CCAPI calls them Component Interface Specs (CIS). Key to facilitating integration in a distributed environment • Generic Interface Design (GID) initial design submitted to IEC 12/2001 after 2 yrs technical debate and design – SW developers create components w/o concern for underlying infrastructure – GID guides standard API for an application to exchange/access data © 2005 Electric Power Research Institute, Inc.

CIM XML Interoperability Tests • EPRI has sponsored six interoperability tests based on the CIM XML standards: – Six interoperability tests successfully completed exchanging real-world large scale models (12, 000 bus) and several sample models (40 to 100 bus) • • • December 2000: Orlando, Florida April 2001: Las Vegas, Nevada September 2001: Monterey, California July 2002: San Francisco, California November 2003: Cleveland, Ohio July 2004: Folsom, California – Validated the use and acceptance of this standard by suppliers who provide products to the electric utility industry – Test reports available from EPRI © 2005 Electric Power Research Institute, Inc.
